摘要：

为了解河北省粗饲料的草食家畜载畜能力和容量，应用2008 年河北省统计资料和相关文献的数字，计算了河北省草食家畜的饲养量，并根据粗饲料产量，计算了河北省粗饲料的草食家畜的饲养潜力。结果表明：（1）河北省草食家畜饲养量折合4428 万个羊单位，对饲草的需求量折合为鲜草量为 8081 万t，折合为干草3 232 万t。（2）河北省总的粗饲料产量折合为9.96×107 t 干草，总的载畜能力为6124 万个羊单位，粗饲料供给总量充足，但饲草供给结构不合理，优质饲草严重短缺，载畜量最大的为农作物秸秆，载畜量为2570 万个羊单位，占饲草总供给的41.97%；青贮玉米和人工草地提供的优质饲草载畜量为1180 万个羊单位，仅占饲草供给的19.26%。因此，优质饲草不足将是限制草食家畜和畜牧业发展的主要因素，开发利用高产优质高效的人工饲草是饲草产业发展的重点和方向。

Abstract:

Based on statistical data of Hebei Province in 2008 and digital data in related literature,the amount of herbivorous livestock in Hebei Province was calculated.And the carrying capacity of roughage for herbivorous livestock in Hebei province was estimated on the basis of the output of the natural grassland,the artificial grassland,the crop straw, the silage maize, the idle farmland,and tree leaf,et.al. The total supply of crude feed can meet the needs of herbivorous livestock.But,the main factor that limited the health development of animal husbandry and herbivorous livestock industry was the lack of high quality forage. The development of high yield, high quality and high benefit of artificial forage will be the focus in the forage industry in Hebei province.
